If you've played the 360 version, you're going to find this hard to believe, but the graphics look even better on the PS3. The colors seem to pop out at you. The movement of the characters shows no flaws. Part of the additional content is added cutscenes. The opening is now over 15 minutes long. Watching it pulls you into Polka's world and before you even play a single step in the game, you're already hooked. You can skip the cutscenes if you really want to, though.
Given that the game is all a dream of Frederic Francois Chopin, of course the music is nothing short of miraculous. Chopin's work has remained popular for centuries after his death. It provides a wonderful background story for an RPG. The voice acting is quite well done too. Salsa is my personal favorite. Where she got that accent from, I will never know! Since all the characters are from different cities and lands, it makes sense that they would sound different. They did a wonderful job of keeping them separate.
